  • Does polyferric sulphate remove algae?
  • Preparation and uses of polyferric sulphate, US Pat., 5,785,862, 1998. Search in Google Scholar Jiang, J. Q., N. J. D. Graham, and C. Harward. Comparison of polyferric sulphate with other coagulants for the removal of algae and algae-derived organic matter.
  • Why are PFS coagulants better than ferric sulphate?
  • Therefore, as the PFS coagulants consist mainly of polymeric species, they exhibit better coagulation behaviour. It is worth noting that for a 90% removal efficiency, only 20 mg/l of PFS are required, whereas the respective dosage of ferric sulphate in this case is much higher, i.e. 30 mg/l.
  • Can polymeric iron sulphate be used for industrial effluent treatment?
  • The combination of PFS with other chemicals or natural coagulants has high potential in treating water or wastewater. This is due to their greater effectiveness and cheaper cost compared to inorganic coagulants and organic flocculants . Previous studies of composite polymeric iron sulphate for different industrial effluent treatments
  • Is PFS a polymeric salt?
  • In polymeric form, PFS is one of the pre-hydrolysing metallic salts with the chemical formula [Fe2 (OH) n (SO4)3−n/2] m (where, n < 2, m > 10) and has a dark brownish red colour as well as is more viscous and less corrosive. PFS has an amorphous structure with small traces of crystallinity, containing both hydroxyl and sulphate functional groups.
